About NAS snapshot overview
By means of Snapshot Client and the NDMP V4 snapshot extension, NetBackup can make snapshots of client data on a NAS (NDMP) host. The client data must reside on the NAS host and be accessible on the client through an NFS mount on UNIX or CIFS on Windows.
A NAS snapshot is a point-in-time disk image. Snapshots can be retained on disk as long as desired. The data can be efficiently restored from disk by means of the Snapshot Client Instant Recovery feature.
Note:
NetBackup for NDMP software is required in addition to Snapshot Client.
See the following diagram for an overview.
In the NetBackup policy, enter the following:
For Windows client:
\\ndmp_hostname\share_name
For UNIX client:
//NFS_mountpoint
Note:
Windows pathnames must use the Universal Naming Convention (UNC).
NetBackup creates snapshots on the NAS-attached disk only, not on the storage devices that are attached to the NetBackup server or the client.
